Test equipment required
The following test equipment is required:
•
a 50 MHz oscilloscope with an external trigger capability
•
a 10× oscilloscope probe with an input impedance of 10 M
Ω
and less than 20 pF
•
a 50
Ω
RF dummy load and power meter rated at a minimum of 100 W RMS (rated
to 1 kW PEP (500 W CW) for high-power amplifier adjustments)
•
an RF signal generator covering the range 400 kHz to 30 MHz, with a calibrated
output of –130 dBm to 0 dBm from a source impedance of 50
Ω
•
a 50 MHz frequency counter with a resolution of 1 Hz
•
a regulated power supply of 13.6 V ±0.2 V at 20 A peak
•
two-tone audio generator operating at 700 Hz and 2300 Hz, with balance control
and adjustable output 0 to 100 mV RMS
•
a digital multimeter with a 10 M
Ω
input impedance
•
an AC voltmeter with a range of 10 mV to 10 V
•
transceiver test unit to Codan drawing
(the microphone isolating
transformer should be fitted with a µ-metal screen to prevent the 50 Hz mains from
being picked up)
•
an RF spectrum analyser capable of measuring intermodulation
•
NGT test handset for use with 2011 RF Units during tests that require a GPIO
connector
